From single-room split systems to fully zoned ducted air conditioning, iNext covers Castle Hill and the rest of the Hills District. Every job starts with a free on-site assessment, so the system we recommend is the right size for your home — not the one that suits us.

Choosing the right system for Castle Hill
The right multi-head split systems setup for a Castle Hill property depends on the building first and the brand second. One outdoor unit — ideal where balcony or yard space is limited
Our technicians work across the Hills District every week, so the recommendation you get is grounded in what actually performs in local homes like yours — not what's sitting in a warehouse. Every quote is free, on-site and fixed in writing.
What affects the price in Castle Hill
- Every Castle Hill home is different, so honest multi-head split systems pricing has to account for your specific job: home size and ceiling height, insulation and glazing, how many zones or rooms you want conditioned, and the installation access at your property.
- The price ranges above reflect real completed jobs across the Hills District. Your free on-site quote converts them into a single fixed written price for your home — valid for 30 days, no obligation.
Local conditions in the Hills District
- Large modern floor plans across the Hills suit zoned ducted air conditioning better than almost anywhere in Sydney — but only when the zoning matches how the home is actually used. We map your family's routine into the design.
- The Hills' hot, still summer afternoons put sustained load on systems, so we size with headroom and recommend smart controls that let you condition only occupied zones.

What is a multi-head split system?
Instead of one outdoor unit per room (as with standard splits), a multi-head system runs multiple indoor heads — wall-mounted, floor console or even slim ceiling cassettes — off a single, larger outdoor compressor. Each head has its own remote and set temperature, so the bedroom can be 22°C while the study stays off.
How much does a multi-head system cost in Castle Hill?
Pricing scales with the number and size of indoor heads and the pipe run lengths between them and the outdoor unit. Two-head systems start around the cost of two quality splits; the savings grow as head count rises, because you’re installing one outdoor unit instead of several. See the table below for typical fully-installed ranges.
Common Multi-Head Split Systems jobs in Castle Hill
- Head sizing per room — bedrooms need far less capacity than open-plan living areas
- Pipe run lengths — multi-head systems have maximum total and per-head pipe lengths we design within
- Outdoor unit placement — one larger unit needs a sensible, serviceable position
- Mixed head types — wall units in bedrooms, floor consoles or cassettes where walls are glass
- Strata approval — we prepare the plans and specifications body corporates ask for
